Is it necessary to clean the throttle valve?

[DiPreston]

Cleaning the throttle valve is indeed necessary. If the engine throttle valve is not cleaned for a long time, excessive dirt can cause the throttle valve to move less flexibly. This allows air entering the engine to carry many impurities, affecting normal gasoline combustion, reducing the engine's working power, and in severe cases, leading to unstable idling, difficulty starting, and decreased power. Additional relevant information is as follows: 1. Throttle valve: The throttle valve, also known as the throttle body, controls the amount of air entering the engine. It is typically controlled by the accelerator pedal—the deeper the pedal is pressed, the larger the throttle valve opening, and the greater the engine's air intake. 2. Sludge: Due to the relatively higher ventilation and lower temperature at the throttle valve, oil vapor produced during engine operation and the carbon deposits mixed within the vapor can easily condense here, forming sludge.
